Feature Choosing involving DX7 Junk

[Juron Pilo]

Allright, I would like to ask that DX7 features be selected seperately. When I turn DX7 on I can use day and night but not the light effects(like what is used in caves or on lamps). In fact, when I run into the light effected areas, day and night seems to shut down untill I alt tab. So, can you make them seperately selectable? Thanks=)
